描述
The Sound Meter app measures ambient noise and displays it in decibels (dB), offering a convenient tool for monitoring your surroundings. With its simple UI and smooth interface, the app provides a pleasant user experience. It visualizes decibel levels in various ways and gives detailed noise analysis results.
Key Features:
Decibel Gauge Display: Displays real-time noise levels in dB, allowing users to easily check the current noise level.
Noise Environment Description: Analyzes the measured noise and provides an explanation of the noise level, such as "Quiet Library" or "Loud Classroom."
Min/Max/Average dB Records: Users can track minimum, maximum, and average noise levels over time, making it easy to monitor changes in noise levels.
Decibel Graphs: Displays the noise level changes over time in a graph, helping users see trends at a glance.
dB Calibration: As different devices may measure noise differently, users can calibrate the dB values for their device to achieve more accurate results.
Notes:
The smartphone's microphone may have limited accuracy compared to high-performance sound meters, especially for extremely loud or quiet noises. Since most microphones are designed for voice frequencies, the measured dB values may not match professional sound meters, so it is best used for reference only.
When measuring noise in shared housing or apartments, note that the readings may differ from professional sound meters.
Example Noise Levels:
0 dB: Complete silence
30 dB: Whisper
50 dB: Typical household noise
70 dB: Vacuum cleaner, blender
90 dB: Highway traffic noise
100 dB: Train horn
120 dB: Airplane takeoff noise
130 dB: Jackhammer at a construction site
140 dB: Jet engine noise
Warning: Prolonged exposure to noise above 80 dB may cause hearing damage, and short exposure to noise above 100 dB can also cause harm. Noise levels above 120 dB pose an immediate risk of hearing damage, and protective equipment is recommended.
Required Permissions:
Microphone: Used to detect surrounding noise and calculate decibel values.
Usage Notes:
Smartphone microphones are typically optimized for voice frequencies (40-60 dB) and may not detect very quiet or loud sounds accurately. It is recommended to calibrate the decibel values before using the app for more precise results.
App Use Cases:
Measuring Neighbor Noise: If you feel your neighbors are too noisy, this app can record noise levels and serve as a reference.
Noise Environment Monitoring: Monitor noise pollution that may affect work or rest by measuring real-time noise levels.
Snoring Recording: Record snoring sounds and check the decibel levels to take necessary actions.
This app is a convenient tool for measuring everyday noise levels, analyzing sound environments, and helping to reduce noise pollution and protect hearing.
